I don't mean to be a bastard, because the design and colours are beyond awesome, but it should be written: "It's quick and totally free!" instead of "It's quickly and totally free!" You want an adjective there, not an adverb.

It's totally ok! English is not my native language and sometimes I made mistakes. I don't have English classes so the only way I have to learn is when someone point my mistakes. I thank you for that! And thank you for your comments
